Phase Boot Process BIOS UEFI 
1 PreBoot MBR/PBR (Bootstrap Code) UEFI Firmware
2 Windows Boot Manager %SystemDrive%\bootmgr \EFI\Microsoft\Boot\bootmgfw.efi
3 Windows OS Loader %SystemRoot%\system32\winload.exe %SystemRoot%\system32\winload.efi
4 Windows NT OS Kernel %SystemRoot%\system32\ntoskrnl.exe

1]  PreBoot

When you lot hitting the ability button, the estimator firmware starts POST or Power-On Self examination together with loads firmware settings. It checks if in that location is a valid disk organization to start the adjacent phase. It’s indicated yesteryear an MBR or original kick record.

2] Windows stuck amongst a blank monitor amongst no activity

BIOS stage is where the organization goes from PreBoot to Loading Windows OS. Its exclusively marked every bit consummate when in that location is no hardware effect inwards the system. So to banking concern friction match if it is a hardware issue:

  • Remove external hardware together with kick again.
